<h1 class="topictitle1">Benefits of journal management</h1>
|
||
|
|
<div><p>The primary benefit of journal management is that it enables you
|
||
|
|
to recover the changes to an object that have occurred since the object was
|
||
|
|
last saved. This ability is especially useful if you have an unscheduled outage
|
||
|
|
such as a power failure.</p>
|
||
|
|
<p>In addition to powerful recovery functions, journal management also has
|
||
|
|
the following benefits:</p>
|
||
|
|
<ul><li>Journal management enhances system security. You can create an audit trail
|
||
|
|
of activity that occurs for objects.</li>
|
||
|
|
<li>Journal management allows you to generate user defined journal entries
|
||
|
|
to record activity, even for objects that do not allow journaling.</li>
|
||
|
|
<li>Journal management provides quicker recovery of access paths if your system
|
||
|
|
ends abnormally.</li>
|
||
|
|
<li>Journal management provides quicker recovery when restoring from save-while-active
|
||
|
|
media.</li>
|
||
|
|
<li>Journal management provides the means to recover an object that was saved
|
||
|
|
with partial transactions.</li>
|
||
|
|
</ul>
|
||
|
|
<p><img src="./delta.gif" alt="Start of change" />Save your server while it is active has instructions
|
||
|
|
for saving an object with partial transactions. See the example below for
|
||
|
|
instructions about recovering objects with partial transactions.<img src="./deltaend.gif" alt="End of change" /></p>
